Specific embodiment
The half directly-drive permanent magnet electric machine structure of the present invention is subtracted as shown in Figure 1, being directly driven using low-speed half direct-driven magneto
Fast machine operation, cancels original asynchronous machine, belt pulley and belt.Simultaneously according to its practical service condition, to electric machine structure into
Row optimization, half directly-drive permanent magnet main component of electrical machine include：Adjusting washer 4, connection end cap 5, motor stator 8, axle sleeve 13, axle sleeve gear
Plate 12, rotor 10, bearing 14 and end plate 15.
Concrete structure is as follows：7 inside installation motor stator 8 of motor casing, motor stator 8 are equipped with machine winding 6, and motor is fixed
By seam allowance location and installation in connection end cap 5 and passing through screw and fixing, connection end cap 5 is fixed on by screw to be subtracted for sub 8 one end
On fast casing body 2,8 other end of motor stator is fixed on by screw on end plate 15, and speed reducer input shaft 3 runs through reducer shell
2 and connection end cap 5 be installed on 7 inner connecting end lid 4 of motor casing and connect with 7 rear end of motor casing, 3 end of speed reducer input shaft passes through axis
13 connection rotor 10 of set, 10 end of rotor are equipped with magnet steel 9, and 13 front end of axle sleeve is equipped with groove 17, and axle sleeve baffle 12 is pacified
Loaded in groove 17 and passing through screw and being fixed on speed reducer input shaft 3, install and adjust between connection end cap 5 and bearing in reduction gears 18
Whole washer 4.Upper head plate 16 and bottom plate 15 are installed in 7 forepart of motor casing up and down, it is corresponding between upper head plate 16 and bottom plate 15 to slow down
Lid 15 is installed at machine input shaft 3, lid 15 is secured by bolts on upper head plate 16 and bottom plate 15, upper head plate 16, bottom plate 15,
Single-groove grooved ball bearing 14 is installed between connection end cap 5 and rotor 10；The iron core axial length of rotor 8 is more than motor
5 iron core axial length of stator.
Motor stator 8 is fixed by connection end cap 5 and reducer shell 2, by rotor 10 by axle sleeve 13 with subtracting
Fast machine input shaft 3 is fixed, and motor stator 8 is fixed when motor is powered, then rotor 10 drives speed reducer input shaft 3 to revolve
Turn, drive pumping unit operation.Wherein, adjusting washer 4 is used to hold out against 18 outer shroud of bearing in reduction gears；Axle sleeve 13 is according to different model
Speed reducer input shaft structure, size are adjusted, and are processed convenient for rotor 10 is unified；Axle sleeve baffle 12 is with being used for fastening shaft sleeve
13 with rotor 10.10 iron core axial length of rotor is slightly larger than 8 iron core axial length of motor stator so as to effectively avoid
